Microprocessor Supervisory with Manual Reset Input CXDR7599 supervisory circuits monitor the power supply voltage in microprocessor and digital systems

The CXDR7599/CXDR75100 supervisory circuits monitor the power supply voltage in microprocessor and digital systems. The CXDR7599/CXDR75100 is designed to monitor seven different voltages; these voltages have been selected for the effective monitoring of 1.8V, 2.5V, 3V, 3.3V and 5V supply voltage levels.

They provide a reset output during power-up, power-down and brownout conditions. On power-up, an internal timer holds reset asserted for 240ms. This holds the microprocessor in a reset state until conditions have stabilized. The /RESET output remains operational with V_CCas low as 1V. The CXDR7599 provides an active low reset signal (/RESET) while the CXDR75100 provides an active high signal (RESET) output.

The CXDR7599/CXDR75100 has a manual reset input. The manual reset function is very useful, especially if the circuit in which the CXDR7599/CXDR75100 is operating enters into a state that can only be detected by the user. Allowing the user to reset a system manually can reduce the damage or danger that could otherwise be caused by an out-of-control or locked system. The devices come in SOT-143 and SOT-23-5 packages.
